a sin le way rotary Water motor, which is opera Il? connected so as to receivejts operating u id 4from the pressure side of the \valve, and convey motion to the valve oper- 'ating mechanism to open Vand close said valve, aseries of clutches beingprovided to accomplish this result, and convert the continuous movement of. the 'motor in a single direction into motion to operate the valve in two directions, that is to close or open. p

To.clearly illustrate my invention, atten tion is invited to the accompanying drawgure lfs an elevation of a single Way rotatable horizontal Awater motor connected in operable relation to a horizontal gate valve. Fig.- 2 is a top plan thereof. Fig. 3 isan enlarged detail view ofthe clutch mechanism, as shown in Fig. 1. Fig. 4 a

.view'on line -r, Fig.. 3 looking toward the clutches. Fig. 5 shows a vertical single wa rotatin Water motor installed, and Fig. 6 is a. top p an view thereof.

Referring to the drawings z--the numeral 1 designates the vault, in which is mounted the l horizontal gate valve and its casing 2, which is connected-to control the water main 3. This valve, as usual, is provided with the exterior operating mechanism 4, embodying the key-shaft 5, to which, I removably connect t e short key 6, which is connected to the lower member 7 of the iexible jointed clutch 8, the shaft 9, having a ball-and-.

socket connection, not shown, in the member 7', and passing upwardly through the sliding keed member 10, of the clutch which' ismanua y controlled through the medium jfthe leverll. This shaft 9, is jouinal'ed in the c'asting 12, in whose open portion 13,

Y .-.and upon .the shaft 9 is wslidabjly keyed the collar 14carryiiigfthe two oppositely bev'- 16d gears orv pinions 15 and '15', a lever 16 Patented Ju1y'6,11909.

being employed to slide the collar and conse-54,55

quently the gears, so thatche at a time will mesh with and be en aged by the small bevel Binionor gear 17, which is carried upon the orizontal shaft 18.. This horizontal shaft is journaled in the casting at 19, and carries the bevel gear or pinion 20, which meshes at all ,times withjthe bevel gear or pinion 21,

carried upon the lower end of the vertical shaft 22, which is journaled in the casting at 23, and parallel with the shaft 9.v This shaft has keyed thereon the large gear wheel 24, which at all times meshes with the small gear -or pinion 25, which is keyed u on the lower end of the Inotors vertical s aft 26, the motor being mounted in the casing 27, and capable'of a rotarycmotion in only one way. This is by reason of the water conductin pipe 28, which has the two branches 29 an 29", each leading to its side of the valve and attached t the main, so that pressure may always be had `from the pressure side of the valve. To vadmit pressure through the pipe 28, one -ofthe valves 30 or 30 is operated, and water 1s allowed to enter the pipe 28,"thenozzle 31 of the motor, where it acts upon the motor wheel, not shown, and finally exhausts or discharges from the casing into the discharge pipe 32, which leads to a drain in the vault. This constitptes the mechanism for a single way horizontal water rotarv water motor 33, having the water su ply pipe 34 withits branches 35 and 35 t e motors nozzle 36, and discharge 37. The

branches .35 and 35', are provided with the manuall operated valves 30 and 30 respectively, thus allowing control of the iiow of water through either of the branches. to the motor. In this instance the motor has a horizontal shaft 26', instead of a vertcalshaft, and the casting or frame 1 2, is attached to andarried by the inner side Oi the motor casing instead of the bottom; and Vfurther the single bevel pinion' or gear 381s adapted to be engaged,`nne at a .time by the two bevel gears 39 and 39', which are car ried upon the collar 40, which is s'lidably keyedl upon the verticalshait'41, this shait being journaled in the frame 12', and carrying upon its lower end the clutch 42, which is similar to the clutch heretofore described.

bevel pinions 17 or 38.- flhe desired one of the gears'of the gear clutch is now thrown into mesh with the pinion 17 or 38, and thus the vertical shaft carrying the sliding member of the other clutch is rotated. To cause a rotary motion tol be imparted to the key' 20 shaft, the lower clutch is now operated, and

motion is thus transmitted to the valve operating vmechanism from the motor. When l it is. desired to reverse this motion, the

clutches are thrown' out in order, and the other of the gears of the gear clutch is thrown in, and the operation continues as above set 'forth The lever 16 or 44, as clearly shown in Figs. 1, 3 and 5, is each provided with the two coiled springs 44', both of which normall hold the lever in the position shown in Eigs. 1, 3 and 5, so thateither set of gears 15 and 1'5"or 39and 39 isout of engagement with the gear 17 or 38, respectively,

"thus allowing the motor to runiijee without normally alecting thegears 15 and 15 or 3.9 and 39', respectively. The operating lever 11 or 46, is also provided with the s ring 46', which automatically throws out 40 t e clutch- 8 or 42 and' holds it out, both oi' the clutches being normally, out, so that no motion from `the motor is transmitted to the valve operatin mechanism, until the levers 16 or 44, an 11 or 46, 'are manually o erated and held by the o erator. By t is means, it makes it compullsory for the person operating the machinel to stand by the same, and thus avoid damage to the machine or valve during the opening or closing of the valve.

' What I claim, as new is 1. In combination with a water main, a valve mounted therein, operating mechanls'm for the valve, two pipes in communica- Ation with the water Vmain at the respective sides of the valve and adapted to. convey water from the main, a manually operated valve mounted .in each of said pipes t o conf/ trol the flow of water from the main therethrough, and a single pipe into which both of said pipes lead, of a sing e way rotating water motor in communication with said single pipe, rwhereby the Water is'conducted from the main to the motor through either one of the valve controlled pipes, and means for operaoiy connecting the motor to the valve operating mechanism to open or close the valve. p

2. In combination with a water main, a

. valve mounted therein, operating mechanism for the valve, two pipes in communication with the wwater main at the respective sides of the valve and adapted to convey water from the main, a manually operated valve mounted in leach of said pipes to con- 'trol the flowvof water from the main therethrough, and a single pi e into which both of said pipes lead, of a single way rotating water motor in communication with said single pipe, whereby the water is conducted from lthe main to the motor through either one of the valve controlled pi es, and a clutch for operably connecting t e motor with the valve operating mechanism, whereby the motor operates the valve o erating mechanism to open orl close the va ve.

3. In combination with a'water main, la valve mounted therein, operating mechan- 'ism for the valve, two pipes in communication with the water main at the respective sides ,of' the valveand adapted to convey water from the main, a manually'operated valve mounted in each of said pipes to control thd flow of water from-the main therethrough, and a single pipe into which both of said pipes lead, of a sing e way rotating water motor in communication withL said single ,p

pipe, whereby the water is conducted from the main to the motor through either one of the valve controlled pi es, and two clutches interposed between sai motor and the valve o erating mechanism, one of the clutches allowing the motor and the "other clutch to run free without affecting the valve `operating mechanism, or connecting the `same to cause the motor to operate the valve operatl'in mechanism, and the other clutch deterv mining the direction of rotation ofthe valve operating mechanism. 1

a4. In, combination fwith 'a water main, a valve casing mounted therein, a valve in said casing, operating mechanism for the valve, and conduits for conveying water' away from the main at each side of the valve casing, of a single way rotating vertical water motor mounted to one side of the valve casing, a frame carried by said motor casing and oposed to the valve o erating mechanism, a

vertical shaft journa ed in saidA frame and .adapted to re'ceive motion from the water motor, and means vfor o erabl lconnecting said vertical shaft'with t e va ve o eratin meclanism to open or close the va ve, sai wate motor receiving its operating fluid from .the main through said conduits. I
